    • Obtaining sustainable and inclusive societal organization is not merely a simple matter of ‘doing it’ by subscribing to some winning formula. Given that conceptual frameworks always guide our thoughts, judgments and actions (Latour, 2013; Harvey, 1996; Dennett, 1993), the ways in which we relate to concepts chosen to serve as guiding forces for future development will eventually determine its outcome. As scholarly evidence continuously suggests the concepts ‘rural’ and ‘urban’ are increasingly recognized as artificial barriers for conducting sound and integrated development endeavors in a globalized reality of interconnectedness. In line with the Sustainable Development Goals, which aim to eradicate poverty, shield the planet and safeguard prosperity for all, commitment to universal access to healthy food year round has become an important agenda point. This, however, has been exacerbated by binary thinking and separate ways of doing policy. This paper aims to share experiences from a unique project launched in the northern parts of Gothenburg, Sweden’s second largest city. While the area offers ample resources and immense opportunities for areal economies, it at the same time remains one of Gothenburg’s most segregated, with high levels of unemployment, ill health and crime. The uniqueness of the project lies not only in its way of abridging the rural-urban divide, but also by consciously deferring from the debilitating rhetoric of previous ‘immigrant policies’, and instead focusing on agricultural productivity, small-scale food producers and sustainable food strategies. Such exhortations to bridge between philosophical and material polarities, however, have not come without conceptual and practical challenges, something this paper aims to subsume and open up to debate.

  • Key urban projects: Local-regional planning tools for fragile urban landscapes
  • 2014
  • Ingår i: World in Denmark 2014: Nordic encounters. Travelling ideas about open space design and planning.
  • Konferensbidrag (refereegranskat)abstract
    • In Sweden, cities are promoted as drivers of economic growth and solutions for decreased climatic influence, resulting in a dominant focus on development of large cities in the planning debate and sustainability discourse. As discussed by Harvey (2006), Massey (2007) and Tietjen (2011), this increases differences between growing and declining cities and regions, and escalates uneven geographic development. The process produces fragile urban landscapes, i.e. local situations short of resources, skills and mandates to handle change and deal with in-lock of sense-making structures, thereby concealing actual site specific possibilities and the potential of development of small towns and rural areas. This renders the need for new relevant planning tools with onset in a relational perspective on space (Harvey 2006, Massey 2007), urban ecologies (Guattari 1989, Banham 1971) and design-based, proformative approaches (Solà Morales 2008, Bunschoten 2001, Cuff & Sherman 2011). This article argues for key urban projects as a relational, place-specific, operative planning tool that can open and lock urban transformation, secure and guide implementation and reveal strategies to develop fragile urban landscapes, with ability to: handle centre-periphery and urban-rural as dynamic contingencies; combine the capacity of different urban ecologies; relate the formation of urban landscapes to different scales; optimise combinatory potentials of local-regional resources; secure forms of operative collaboration; trigger critical negotiations; and integrate spatial implementation to the planning process. These abilities are tested through design-based research-methodology with onset from works in progress in five Swedish contexts of practice that outline a spectrum of important characteristics of fragile urban landscapes. Key Urban Projects are identified and developed through a mapping process iterating between identification of specific issues and the outline of their relevant contours, a process that both visualize and establish assemblages (DeLanda 2006). Key Projects gain their potential through stepwise change of the existing material landscape and its urban ecologies.

  • Energy and climate-efficient construction systems Environmental assessment of various frame options for buildings in Brf. Viva
  • 2018
  • Rapport (övrigt vetenskapligt)abstract
    • In the collaborative forum Positive footprint housing® Riksbyggen is building the Viva residential quarter, which is a sustainability project at the very forefront of what is possible with contemporary construction. The idea is that this residential quarter should be fully sustainable in ecological, economic and social terms. Since 2013, a number of pilot studies have been completed under the auspices of the Viva project framework thanks to financing from the Swedish Energy Agency. The various building frame alternatives that have been evaluated are precast concrete, cast in-situ concrete and solid wood, all proposed by leading commercial suppliers. The report includes a specific requirement for equivalent functions during the use phase of the building, B. An interpretation has been provided that investigates the building engineering aspects in detail, as well as an account of the results based on the social community requirements specified in Viva, durability, fire, noise and energy consumption in the Swedish National Board of Building, Planning and Housing building regulations (BBR), plus Riksbyggen’s own requirements, Sweden Green Building Council’s Environmental Building Gold (Miljöbyggnad Guld) and 100-year life cycle. Given that the alternatives have different long-term characteristics (and also that our knowledge of these characteristics itself varies), these functional requirements have been addressed by setting up different scenarios in accordance with the EPD standard EN 15978. Because Riksbyggen has specified a requirement for a 100-year life cycle, we have also opted for an analysis period of 100 years. The results show no significant differences between concrete and timber structures for the same functions during the life cycle, either for climate or for primary energy. The minor differences reported are accordingly less than the degree of uncertainty involved in the study. The available documentation on the composition of the relevant intumescent paint coating on solid wood frames differs from source to source, so it was not possible to fully allow for the significance of this. The LCA has not included functional changes in the building linked to load-bearing characteristics, noise, moisture, health or other problems that may result in increased maintenance and replacement. The concrete houses have been dimensioned for 100 years, for instance, in accordance with tried and tested standards and experience. The solid wood house is not dimensioned in the same way, and this has led to us having to assume various scenarios.The results also show the following:• The uncertainties involved in comparing different structures and alternative solutions are very significant. The results are affected by factors such as life cycle, the functional requirements taken into consideration, transportation, design and structural details, etc.• Variations in the built items and a considerable degree of uncertainty in the assumptions make it difficult to obtain significant results on comparisons. Only actual construction projects with known specific data, declared from a life cycle perspective that takes into account actual building developer requirements and involving different scenarios (best, documented and worst-case) for the user stage can currently be compared.• In the other hand, comparisons restricted to different concrete structures only, or to different timber structures only, ought to involve a lower degree of uncertainty. These would then provide results that are significant as well as improvement requirements that are relevant.• There is potential for improving concrete by imposing requirements on the material• There is potential for improving solid wood frames by developing and guaranteeing well-documented long-term characteristics for all functional requirements.The LCAs were performed as an iterative process where all parties were given the opportunity to submit their viewpoints and suggestions for changes during the course of the work. This helped ensure that all alternatives have been properly thought through.Because, during the project, Riksbyggen opted to procure a concrete frame, in the final stage the researchers involved focused on ensuring the procurement process would result in the concrete frame as built meeting the requirements set out above. As things currently stand, the material requirements for the concrete are limited by the production options open to the suppliers, and this is therefore being investigated in the manufacture of precast concrete frames for the Viva cooperative housing association.

  • The urban form and the sound environment - Tools and approaches
  • 2017
  • Licentiatavhandling (övrigt vetenskapligt)abstract
    • Cities are always confronted with transition and adaptation. Awareness on urban environmental quality is leading the vision about the built environment’s resilience and sustainability, highlighting the importance of a multidisciplinary framework for urbanisation processes. One of the main concerns is the negative impact of outdoor noise due to road traffic, whereby controlling the sound environment through good quality spatial production is a priority. Europe and other parts of the world are experiencing a chronic traffic congestion problem. The environmental impact of this situation is overwhelming, where 90 % of the health impact due to noise exposure is estimated to be caused by road traffic noise. In this regard, noise maps are seen as a powerful tool in the development of new urban areas, where its noise level underestimation can endanger the wellbeing of citizens. At this rapid urbanisation, divided pronouncements on decision-making are devastating. The aim is to overcome negative aspects derived from a late intervention by including urban sound planning as an opportunity to the user’s experience and wellbeing, avoiding poor patches in the urban configuration and economical burden. The present work is committed to the development of tools for controlling, communicating and designing the sound environment on a level beyond today’s solutions, capable to be included at the early stages of the planning process. First, the study goes through the importance of the quiet side and the implementation of an engineering method as a powerful tool in the urban development, obtaining accurate results compared to measurements. In an attempt to study time variations of traffic within cities and its relevance regarding noise emission (normally overlooked in current noise mapping calculations), a microscopic road traffic modelling tool is developed in the second study, giving useful output for noise level predictions as function of time. The time-pattern analysis opens the possibility to test traffic configurations and explore a large variety of results in the form of descriptors as statistical indicators, calm periods and noise events, and outcomes as difference maps and contribution maps. The third study extends toward the evaluation of the effects of spatial heterogeneity (considered a key strategy to increase the liveability of spaces) on the environmental performance and resilience capacity of the transportation system through the study of noise pollution and its economic impact. The studies presented are using real case scenarios as a test-bed not only for implementation, but mainly for the development of tools.

  • Nachhaltig bauen - Lebenszyklus, Systeme, Szenarien, Verantwortung
  • 2011
  • Bok (övrigt vetenskapligt)abstract
    • Dem Bauwesen kommt bei der Zielsetzung einer Nachhaltigen Entwicklung eine grosse Bedeutung zu. "Nachhaltig Bauen" bedeutet vereinfacht ausgedrückt, Bauwerke zu errichten und zu erhalten, die ein Kapital für zukünftige Generationen darstellen und keine Altlast. Das Buch bietet einen Einstieg in diese Thematik über drei Zugänge: Denkschule, Handwerkszeug und Beispiele. Es wird der bestehenden Baupraxis ein Ansatz gegenübergestellt, der sich am gesamten Lebenszyklus der Bauwerke orientiert und ein Denken und Planen in Systemen und Szenarien voraussetzt. Dies erfordert ein modernes Selbstverständnis des Planenden, der bei sämtlichen Prozessen der Planung und Bewirtschaftung die Verantwortung übernimmt und sich nicht nur auf den Entwurf beschränkt. Beispiele Nachhaltigen Bauens veranschaulichen mögliche Lösungsansätze und zeigen auf, welche Ideen funktionieren oder wo noch optimiert werden kann. Ein Anhang mit einer umfassenden Übersicht zu Instrumenten für Nachhaltiges Bauen ergänzt die Publikation. - Umfasst den ganzen Lebenszyklus von Bauten, von der Herstellung über die Nutzung bis zur Entsorgung. - Thematisiert viele Teilbereiche: u.a. Projektmanagement, Life Cycle Management, Facility Management, Immobilieninvestition. - Enthält einen umfassenden Anhang zu Instrumenten und Hilfsmitteln.

  • Approaches to Safeguarding Sustainability Requirements in Public Construction Projects – the Client’s Perspective
  • 2016
  • Ingår i: CIB World Building Congress 2016.
  • Konferensbidrag (refereegranskat)abstract
    • In recent years, the concept of sustainability has penetrated much of modern political, social and industrial discourse. Its recent popularization, stemming from the Brundtland report of 1987, has led to sustainability becoming a household term in nearly every industry, of which the construction sector is no exception. Considering the importance that sustainability has in the construction industry, and how it is particularly emphasized in construction financed by public funds, questions need to be raised in terms how capable the construction client is in meeting and achieving the sustainability requirements, often set by politics, that exist whilst safeguarding project delivery. The study is based on four interviews targeting public clients in Sweden and it investigates how sustainability requirements are managed in large public construction projects. What is of particular interest is the degree to which public client organizations either develop or procure systems/staff to ensure that the criteria for social, environmental and cultural sustainability are maintained and that the consequences of different approaches are managed. The results support the idea of having a multifaceted approach to sustainable construction, arguing that terms such as social and cultural sustainability may instead be dealt with separately from the more strictly defined sustainability terms of toxicity, waste and energy consumption. There is also a suggestion that once the client organization begins incorporating a sustainability mind-set in all of its affairs, members of that organization may begin working with sustainability on a perfunctory basis without necessarily understanding the underlying reasons for their actions. Finally, the challenge with sustainability is perhaps not so much that there is a lack of capability as much as there is a lack of resources for working with sustainability.

  • Propositional architecture and the paradox of prediction
  • 2015
  • Ingår i: Archidoct Vol. 4. - 2309-0103. ; 4, s. 72-85
  • Tidskriftsartikel (refereegranskat)abstract
    • What if we could predict trends, rising phenomena and future necessity in our build environment? If we could trace behaviors and forecast the needs for the future? If we had a tool for proposing architecture, that was able to point out potentialities and suggest additions, subtractions and modifications. If Architects had a tool to predict future demands, modification of the build environment could meet the changing behaviors and emerging phenomena in society. Research on existing building stock is reviewed in a context where prediction on complex indeterminate environments is possible. And an entirely new type of architectural tool is proposed, an algorithm for prediction. The algorithm, capable of making prediction in unstructured environments, is presented, and basis and idea of the algorithm is described in detail. The discussion focus on possible applications for this new tool, and the paradox of prediction is debated. Finally, improvements to the computational system are proposed.
